Title (EN) LOW PROFILE LAMP USING TIR LENS
(FR) LAMPE À PROFIL BAS UTILISANT UNE LENTILLE À RÉFLEXION INTERNE TOTALE
Abstract:
(EN) A lamp is provided which is suitable for use in low-profile applications. The lamp includes a light source and a lens. The lens includes a first surface opposite a second surface, where the second surface includes an injection surface and the first surface includes a multi-faceted optical element converging towards the injection surface. The light source injects light into the lens via the injection surface and the light refracts through the first surface while total internally reflecting off the first surface and the second surface toward the periphery of the lens.
(FR) L'invention porte sur une lampe, qui est apte à l'utilisation dans des applications à profil bas. La lampe comprend une source de lumière et une lentille. La lentille comprend une première surface opposée à une seconde surface, la seconde surface comprenant une surface d'injection et la première surface comprenant un élément optique à multiples facettes convergeant vers la surface d'injection. La source de lumière injecte de la lumière dans la lentille par l'intermédiaire de la surface d'injection, et la lumière se réfracte à travers la première surface tout en subissant une réflexion interne totale à partir de la première surface et de la seconde surface vers la périphérie de la lentille.
